Unreleased

  • Added optional combinator.
  • Renamed Dummy to Select.
  • Renamed Column to Expr.
  • Changed Expr to be co-variant in its lifetime.
  • Rows::into_vec is no longer sorted automatically.
  • Added safe updates of a subset of columns for each table.
  • Update statements now use the Update type for each column.
  • Migrations now allow renaming tables and splitting tables.
  • Migrations now require explicit handling of potential unique constraint violations.
  • Migrations now require explicit handling of foreign key violations.
  • Added a macro for each table to create ad-hoc column selection types.
  • Added the FromExpr trait to allow custom column selection and conversion.
  • TransactionWeak::unchecked_transaction is no longer behind a feature flag.
  • hash_schema method was moved behind dev feature.
  • Updated dependencies.
  • Added support for Vec<u8> data type (sqlite BLOB).
  • Renamed try_insert to insert and insert to insert_ok.
  • Renamed try_delete to delete and delete to delete_ok.

0.3.1

  • Added error message when defining an id column.
  • Added support for sqlite LIKE and GLOB operators.
  • Added support for DELETE using TransactionWeak and #[no_reference].
  • Added TransactionWeak::unchecked_transaction behind feature flag.
  • Added impl ToSql for TableRow behind unchecked_transaction feature flag.
  • Removed impl RefCast for Transaction, it was not intended to be public.
  • Removed impl FromSql for TableRow, it was not intended to be public.

0.3.0

  • Added support for updating rows.
  • Added Table::dummy method, which makes it easier to do partial updates.
  • Reused table types in the generated API for both naming TableRow<User> and dummies User {name: "steve"}.
  • Forbid Option in unique constraints.
  • Renamed ThreadToken to LocalClient.
  • Renamed and moved read and write_lock to transaction and transaction_mut.
  • Check schema_version at the start of every transaction.
  • Simplify migration and borrow LocalClient only once.
  • Renamed Prepare to Config and simplified its API.

0.2.2

  • Bound the lifetime of TableRow: IntoColumn to the lifetime of the transaction. Without the bound it was possible to sneak TableRows into following transacions.
    query_one now checks that its input lives for as long as the transaction. To make sure that query_one still checks that the dummy is "global", the transaction now has an invariant lifetime.

0.2.1

  • Relax Transaction creation to not borrow the Database.
  • Add missing lifetime bound on try_inserts return value. Technically this is a breaking change, but it fixes a bug so it is still a patch release.
  • Fix the version of the macro crate exactly (=0.2.0) to allow future internal API changes with only a patch release.

0.2.0

  • Rewrote almost the whole library to specify the schema using enum syntax with a proc macro.
  • Added a single Column type to handle a lot of query building.
  • Dummy trait to retrieve multiple values at once and allow post processing.
  • Added support for transactions and multiple schemas.

0.1.x

  • This version was SQL schema first. It would generate the API based on the schema read from the database.
